Added a new setting to dungeon pack configs called "DuplicateSearchLevels", which allows us to configure how many levels up of the dungeon tree should be checked to avoid duplicating rooms used in that subtree. In other words, it lets us avoid repeating rooms used in neighboring branches of the dungeon. The setting has been added but it's not fully supported yet - some additional code is needed in DungeonHelper and it's not trivial to implement. I took a break because doing it wrong could break dungeon selection.
